When it comes to dealing with password-protected Excel files, we sometimes find ourselves in a tight spot. Have you forgotten the password to an important spreadsheet, or maybe you acquired a file that’s locked and you need access? Fear not! In this guide, we’ll explore safe techniques for cracking Excel password-protected files, ensuring you know the right path to recover your data without falling into any digital traps.
Understanding Excel Password Protection
Before we dive into the techniques, it’s crucial to understand how Excel's password protection works. There are two types of passwords used in Excel:
- Open Password: This password is required to open the file.
- Modify Password: This password restricts editing of the document but allows viewing.
Both types serve to protect sensitive information, so we should respect that. However, if you find yourself locked out, the following tips will help guide you through safe and effective methods for regaining access.
Basic Techniques to Bypass Excel Passwords
1. Using VBA Macro
This is a well-known technique among Excel users for dealing with the Open Password issue. Here’s how you can do it:
-
Open Excel and create a new workbook.
-
Press
ALT + F11
to open the VBA editor. -
Insert a new module by right-clicking on any of the items in the Project Explorer, selecting
Insert
, thenModule
. -
Copy and paste the following VBA code into the module:
Sub PasswordBreaker() Dim i As Integer, j As Integer, k As Integer Dim l As Integer, m As Integer, n As Integer Dim password As String Dim wb As Workbook Dim myFile As String Dim found As Boolean myFile = Application.GetOpenFilename() If myFile = "False" Then Exit Sub Set wb = Workbooks.Open(myFile, Password:="") On Error Resume Next For i = 65 To 90 ' ASCII for A-Z For j = 65 To 90 ' ASCII for A-Z For k = 65 To 90 ' ASCII for A-Z For l = 65 To 90 ' ASCII for A-Z For m = 65 To 90 ' ASCII for A-Z For n = 65 To 90 ' ASCII for A-Z password = Chr(i) & Chr(j) & Chr(k) & Chr(l) & Chr(m) & Chr(n) wb.Close False Set wb = Workbooks.Open(myFile, Password:=password) If Not wb Is Nothing Then MsgBox "Password is: " & password found = True Exit Sub End If Next n Next m Next l Next k Next j Next i If Not found Then MsgBox "Password not found." End Sub
-
Run the macro by pressing
F5
. This will start the process of brute-forcing the password.
This technique may take some time, depending on the complexity of the password.

When choosing software, ensure it has positive reviews and reliable customer support to help with any issues.
3. Using Previous Versions
If you have backups enabled or use OneDrive or SharePoint, you can restore the previous version of the Excel file before the password was set. Here’s how to do it:
- Right-click the Excel file in Windows Explorer.
- Select Properties and go to the Previous Versions tab.
- Look for an older version and click Restore.
This is a straightforward method and doesn’t involve complex techniques or tools.
Advanced Techniques
1. Hex Editor Method
This method is technical and requires a basic understanding of hex editors. Follow these steps:
- Make a copy of the Excel file.
- Open it in a hex editor (such as HxD).
- Locate the password data (usually in the second or third section).
- Change the specific bytes associated with the password.
- Save the changes and reopen the file in Excel.
This method can be risky and is not recommended for beginners, as it may corrupt your file.
